Vitamin C, total phenol index (TPI), total anthocyanins and polyphenolic compounds by high performance liquid chromatography (HPLC), as main factors responsible for antioxidant activity, were determined.
The fruit of this plant is one of the richest sources of ascorbic acid in the world [6]. The evergreen shrub Acerola, which flourishes in warm and tropical climates, bears a small trilobite cherry-like fruit [7]. From April to November, the tree flowers and the fruit mature in 3-4 weeks after flowering. … In immature stage, the skin color is green, while at the ripening stage, it changes to an orange-red and finally to a bright red color on maturation. Malpighia emarginata not only contains an exorbitant amount of ascorbic acid but also contains several phytonutrients like carotenoids, phenols, flavonoids, and anthocyanins [7]. … They are mostly found in the root, stems, leaves, flowers, and fruits. Malphigia Emerginata fruit contains several important phytoconstituents such as carotenoids, phenolics, flavonoids, and anthocyanins [7] and possesses numerous biofunctional properties. Flavonoids possess various pharmacological activities such as antitumor, antibiosis, antivirus, anti-inflammatory, and so on.
The present work evaluates the antioxidant capacity of hydrophilic extracts of acerola pulps and juices by 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ORAC and 1,1-diphenyl-2-picrylhydrazyl (DPPH) methods.
While acerola's high ascorbic acid content is well-documented, the fruit also serves as a rich source of other phytonutrients, including carotenoids, phenols, flavonoids, and anthocyanins [14,15]. These phytonutrients endow the fruit with various bio -functional and therapeutic properties that are yet to be comprehensively explored.
The present work evaluates the antioxidant capacity of hydrophilic extracts of acerola pulps and juices by 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ORAC and 1,1-diphenyl-2-picrylhydrazyl (DPPH) methods.
The present work evaluates the antioxidant capacity of hydrophilic extracts of acerola pulps and juices by 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ORAC and 1,1-diphenyl-2-picrylhydrazyl (DPPH) methods. Antioxidant activity values obtained for acerola juice were higher than those reported for other fruit juices particularly rich in polyphenols such as strawberry, grape and apple juices, among others.
Flavonoids possess various pharmacological activities such as antitumor, antibiosis, antivirus, anti-inflammatory, and so on.
